NOTICE
Do not remove or insert a C-PLUG / KEY-PLUG during operation!
A PLUG may only be removed or inserted when the device is turned off.
The device checks whether a PLUG is present at one second intervals. If it is detected
that the PLUG was removed, there is a restart. If a valid KEY-PLUG was inserted in the
device, the device changes to a defined error state following the restart. With
SCALANCE M, the available wireless interfaces are deactivated in this case.
If the device was configured at some time with a PLUG, the device can no longer be
used without this PLUG. To be able to use the device again, reset the device to the
factory settings.
Note
Incompatibility with previous versions with PLUG inserted
During the installation of a previous version, the configuration data can be lost. In this
case, the device starts up with the factory settings after the firmware has been installed.
In this situation, if a PLUG is inserted in the device, following the restart, this has the
status "NOT ACCEPTED" since the PLUG still has the configuration data of the previous
more up-to-date firmware. This allows you to return to the previous, more up-to-date
firmware without any loss of configuration data.
If the original configuration on the PLUG is no longer required, the PLUG can be deleted
or rewritten manually using "System > PLUG".
Information about the license of the KEY-PLUG
A C-PLUG can only store the configuration of a device. In addition to the configuration, a
KEY-PLUG also contains a license that enables certain functions of your SIMATIC NET
device.
This page provides detailed information about the license on the KEY-PLUG.
